Question

Is -2pi / 3 = 240 degrees and its Degree Equivalent = 2pi/3 ??

Answer 1

I meant Is -2pi / 3 = 240 degrees and its Degree Equivalent = 120 degrees ??

Answer 2

What you can remember is that pi radians = 180 degrees

Answer 3

I see another boo boo I mean

Is -2pi / 3 = -240 degrees and its Degree Equivalent = 120 degrees??

Answer 4

So you can replace pi with 180 degrees and simplify it

\(\sf\Large \frac{-2(180)}{3}=?\)

Answer 5

Your answer is wrong btw :/

Answer 6

another way to think about it is:

-2pi/3

we are working clockwise on the circle,

and in radians the whole circle is 2pi

so 2pi is also 6pi/3

and so to find out how much we are left at would be:

6pi/3 - 2pi/3 = 4pi/3

Answer 7

-2pi/3 = -120 yes but this is at the 240 mark correct?

Answer 8

correct

Answer 9

and you can see from my second example that 4pi/3 = 240 degrees

Answer 10

Ok lets start over. -2pi/3 = -120 degrees, which is at the 240 mark. Now its Equivalent degree is at 120, which is at 2pi/3 ??

Answer 11

"-2pi/3 = -120 degrees, which is at the 240 mark."

correct

"Now its Equivalent degree is at 120, which is at 2pi/3 ??"

and correct

Answer 12

Ok :-) thank you!

Answer 13

anytime :D
